About Our Colourful Autumn Perennials Collection

At Boma, our autumn flowering collection covers the full sweep of the season, from late summer into mid autumn. Japanese anemones deliver graceful white and pink flower spikes above clean, divided foliage, flowering from August through October. Sedum 'Autumn Joy' forms flat-topped flowerheads that progress from mauve pink to rich bronze as the season advances. For bold flower colour, New York Aster brings blue and purple tones, while Helenium offers bright yellow flowers and orange. All are beautiful flowers suited to a sunny spot or partial shade.

Many autumn perennials prefer well drained soil enriched with organic matter, though hardy sedums and grasses cope with poorer conditions. Planting from bare roots in early autumn allows establishment before winter, while pot-grown plants can go in throughout the season. Many autumn favourites — grasses, sedums, and asters — are best left standing after flowering, as their seed heads and foliage turns to bronze and amber, continuing to attract beneficial insects including bees and butterflies well into early winter.

Boma's autumn perennials selection extends beyond flowering plants to include foliage shrubs and ornamental grasses that carry your outdoor space through early winter and beyond. Euonymus brings brilliant leaf colour as foliage turns in October, while Pennisetum and Miscanthus grasses stand beautifully after the first frosts. As new growth emerges in early spring, the cycle continues with minimum intervention. Whether you're refreshing tired borders or building a garden blooming with colour from late summer through winter, our Kentish Town team can help.

Popular Questions

What can I plant now for autumn garden colour in the UK?
For instant autumn colour, choose pot-grown autumn flowering perennials such as Japanese anemones, Sedum 'Autumn Joy', and New York Aster — all available at Boma in Kentish Town. Bare roots of hardy perennials including Helenium and Rudbeckia 'Goldstrum' can also be planted in early autumn to establish before winter. Ornamental grasses such as Miscanthus and Pennisetum add movement and texture to borders from late summer through the first frosts and beyond.
Can you plant perennials in September in the UK?
Yes — September and October are excellent months for autumn planting in the UK. Soil is still warm from summer, helping roots establish quickly before winter dormancy. Hardy perennials planted now, including Heuchera, Japanese anemones, and Sedum, will settle in and flower the following year. Bare roots planted in autumn often establish more vigorously than spring-planted equivalents. Add a mulch layer after planting to protect new roots through early winter.
What are the best flowering plants for autumn and winter?
The best autumn perennial plants combine reliable colour with structural interest. At Boma, top performers include Sedum 'Autumn Joy', Japanese anemones for graceful white and pink blooms, Helleborus for winter flowers from December onwards, and Cyclamen coum for partial shade ground-level colour. Hardy perennials such as Heuchera provide year round foliage interest, their leaves turning to deeper tones of purple and bronze as temperatures drop through October into early winter.
